The expert was somewhat led astray by my phrasing of the problem. To clarify: 1. The refrigerator was purchased brand new. It was not a demo or floor model. 2. The touch panel on the outside of the door is malfunctioning. Whenever we press on the temperature adjustment for either the freezer or the refrigerator, the number on the readout goes down only. We can't get it to go up. The milk is beginning to freeze in the fridge.The expert was somewhat led astray by my phrasing of the problem. To clarify: 1. The refrigerator was purchased brand new.

Suspicions (nearly) confirmed! This is the only thing that makes sense to me, too. I'll know for sure when I do the actual board swap.Suspicions (nearly) confirmed! This is the only thing that makes sense to me, too. I'll know for sure when I do the actual board swap.

If tempt will not increase i would say the board is bad . and would replace it . sensors also could do this so if both sides do not adjust repl board and if only ref or freezer then do the senor on the side that won't adj . mm

My first thought is that the thermostat is having a problem, but a temperature sensor could be having a problem. Also, and maybe more likely, the defrost thermostat could be bad. Contact the Sear's support site for parts, or call a Sear's Service Center to see what they think it is. Since the defrost thermostat allows the temperature to rise, and hence defrost, it would make sense it's faulty. I would just replace it, since it was a demo (and probably a return that they couldn't figure out).
Good luck, and hope this helps.

Hi Marisa:
Following is the instruction for adjusting the freeser temperature for your Samsung refrigerator:
You press the freezer temperature button repeatedly till you see your desired temperature. If you want to set it to -2F, stop when the display shows -2F and don't press the freezer button again. After 5 seconds this new temperature will be set.

The instructions from the Samsung manual is shown below:
Controlling the Freezer temperature:
The Freezer temperature can be set between 8°F and -14°F to suit your particular needs. Press the Freezer button repeatedly until the desired temperature is shown in the temperature display. Keep in mind that foods like ice cream may melt at 4°F. The temperature display will move sequentially from -14°F to 8°F. When the display reaches 8°F, it will begin again at -14°F. Five seconds after the new temperature is set, the display will again show the actual current freezer temperature. However, this value will be changed to the new temperature.

Controlling the Freezer temperature
The freezer temperature can be set between -14°C (8°F) and -25?C (-14°F) to suit your particular needs. Press the freezer button repeatedly until the desired temperature is shown in the temperature display. Keep in mind that foods like ice cream may melt at -16?C (4°F). The temperature display will move sequentially from -14°C (8°F) and -25?C (-14°F). When the display reaches -14?C (8°F), it will begin again at -25?C (-14°F). Five seconds after the new temperature is set the display will again show the actual current
freezer temperature. However, this number will change as the Freezer adjusts to the new temperature. The top and bottom guards in the freezer of this model are the two star sections, so the
temperature in two star sections are slightly higher than other freezer compartment.

Controlling the Fridge temperature
The refrigerator temperature can be set between 7?C (45°F) and 1?C (34°F) to suit your particular needs. Press the fridge button repeatedly until the desired temperature is shown in the
temperature display. The temperature control process for the Fridge works just like the Freezer process. Press the fridge button to set your desired temperature. After a few seconds, the Fridge will
begin tracking towards the newly set temperature. This will be reflected in the digital display. The temperature of the freezer or the refrigerator may rise from opening the doors too frequently, or if a large amount of warm or hot food is placed in either side. This may cause the digital display to blink. Once the freezer and refrigerator return to their normal set temperatures the blinking will stop.
If the blinking continues, you may need to "reset" the refrigerator. Try unplugging the appliance, wait about 10 minutes and then plug back in.

The refrigerator does not work at all or it does not chill sufficiently.
• Check that the power plug is properly connected.
• Is the temperature control on the display panel set to the correct
temperature? Try setting it to a lower temperature.
• Is the refrigerator in direct sunlight or located too near a heat source?
• Is the back of the refrigerator too close to the wall and therefore keeping air from circulating?

If your AM04 fan heater runs for a few moments then shuts off, this is likely to be because the target temperature you've selected (shown on the LED display on the base of the machine) is lower than the ambient room temperature. The intelligent thermostat is engineered to ensure the machine will only run as needed to maintain the target temperature you've chosen.

Using the remote, or the controls on the base, to raise the target temperature by a few degrees should resolve the issue. I've included our Getting started guide below which shows how to adjust the temperature.

If you would like some further help from our experts after you've given this a try, please call 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU).

To enter Self Diagnostic mode, both temperature control panel displays must be illuminated. A display can be illuminated by pressing an adjacent temperature adjustment button. When both displays are illuminated, set the freezer and refrigerator temperature settings to 5. Simultaneously press and hold all

4 temperature adjustment buttons for approximately 3 seconds. A flashing 0 in the refrigerator and freezer displays will indicate that the refrigerator is in Self Diagnostic mode.

For temperature control panels with single-digit displays, the COLDER temperature adjustment button will increment the numbers up and the WARMER temperature adjustment button will increment the numbers down. Use the freezer temperature adjustment buttons to enter the test code number in the freezer display. Use the refrigerator temperature adjustment buttons to enter the test code number in the refrigerator display. When a test code has been entered, the displays will flash to confirm the test. Press the HOLD button for 3 seconds to begin the test.

For temperature control panels with 3-digit displays, the COLDER temperature adjustment button will increment the numbers down and the WARMER temperature adjustment button will increment the numbers up. Use the freezer temperature adjustment buttons to enter the test code number in the freezer display. Use the refrigerator temperature adjustment buttons to enter the test code number in

the refrigerator display. When a test code has been entered, the displays will flash to confirm the test

code. Press any button other than a temperature adjust button to begin the test.

• Unplug the refrigerator for at least 10 seconds. Test mode will terminate when the refrigerator is plugged back in.
Test mode will terminate automatically after 15 minutes of inactivity.

You need to cycle your freezer display to indicate 0 and your refrigerator display to 7.

Control and Sensor System Self-Test (0 7)

This test checks all five thermistors located throughout the unit. Once the test is initiated, the test code (0 7) will stop flashing and the thermistor test results will appear on the freezer display in the test order listed below. The thermistor test sequence number will not be shown on the display.

If the unit is not equipped with the Quick Chill option, the third thermistor (quick chill) will display a 0 and 3 audible beeps will sound at the temperature control panel. This is not a failure if the unit is not equipped with the Quick Chill option.

Note: Thermistor test results will be displayed in the sequence shown above. The thermistor test sequence number will not be shown on the display.

Note the failures if any. Should ANY of thermistors fail you must replace it.

Having said that... at this point your stick with doing a manual defrost by unplugging the unit and directing a fan into the compartment for just over 2 hours to make sure ALL of the ice on the coils and in the drains has melted. (Yes it makes a water mess!)

After the manual defrost restart the unit / plug it in and once the compressor starts listen for the evaporator fan when the door switch is actuated and the condenser fan in the bottom of the unit any time the compressor is running. If either of the fans are not running you must find out why. Can be a door switch, motor winding or power to the motor. The door switch does not affect the condenser fan.

Finally if the unit is not automatically defrosting due to a component failure... i.e

Heater, themistor, or wiring you will see ice build up again in 2 to 3 days again and you will have to keep going through the manual defrosting routine until the automatic defrosting problem is resolved.

To Adjust the Oven Temperature (do not use Bake or Broil while adjusting the oven temperature): note: Your oven control was factory set in the (Fahrenheit) °F Temperature Display Mode. To change for (Celsius) °C, see page 15.1. Press & hold the BAKE key pad and release after the display shows the factory temperature setting of 00. note: If the oven temperature has been previously adjusted from the factory setting, the current temperature adjusted value will appear in the display instead.2. You may increase the oven temperature in 5°F (1°C) increments with each press of the uP arroW pad to a maximum oven adjustment of +35°F (+18°C). You may also adjust the oven temperature downward in 5°F (1°C) increments with each press of the doWn arroW pad (total range of -35°F to +35°F (-18°C to +18°C).3. If you do not want to keep the display adjustment, press the clear oFF pad before the oven control beeps. This will cancel the temperature adjustment procedure. To start this procedure over again begin with step 1 above OR;4. If you want to keep the adjustment, wait until the oven control beeps once.5. The oven temperature adjustment has be accepted by the oven control and the display will return to the time of day.

First, run the control and thermistor test:

Control and Sensor System Self-Test (0 7)This test checks all five thermistors located throughout the unit. Once the test is initiated, the test code (0 7) will stop flashing and the thermistor test results will appear on the freezer display in the test order listed below.

Oven Temperature Adjustment Option for the MSG5770If you think the oven should be hotter or cooler, you can adjustit yourself. To decide how much to change the oven temperature,set the temperature 25°F higher or lower than the temperaturein your recipe, then bake. The results of the “test” shouldgive you an idea of how much to adjust the temperature.To adjust the oven temperature:1. Press the BAKE pad.2. Enter 550° by pressing the number pads “5, 5, 0”.3. Press and hold the BAKE pad for several seconds until 0°appears in the display.4. Press any number pad to change the temperature. Each timea pad is pressed, the temperature changes by 5°F.• Press repeatedly to reach +35°F. Continue pressingto reduce the temperature up to -35°F.• If the oven temperature was previously adjusted, thechange will be displayed. For example, if the oventemperature was reduced by 15°, the display willshow -15°.5. When you have made the adjustment, press theCANCEL pad and the time of day will reappear in thedisplay. The oven will now bake at the adjustedtemperature.NOTE: Do not change the temperature setting more than10° at a time before testing the oven.It is not necessary to readjust the oven temperature if thereis a power interruption. This adjustment will not affectbroil or clean temperatures.

This is a simple fix as long as the oven is heating properly and the only problem is that the temp seems higher than what the temperature control knob indicates...

Purchase an inexpensive oven thermometer from the hardware store and place it in the center of the oven. Set the temperature control knob to 350 degrees F.

Check the temperature indicated on the thermometer in the oven after 20 minutes. If it's not within 5 degrees of 350, you'll need to adjust the oven's temperature control.

Turn the oven off.

Pull off the temperature control knob. You can usually pull it off by hand, pry it off with a thin screwdriver, or slide a piece of cord up behind it and pull.

Note which kind of temperature control knob you have. There are two types: The first has a screw in the shaft of the knob; the second has an adjustment dial on the back of the knob.

Adjust the temperature with the first type by turning the screw in the shaft with a screwdriver. Turn it clockwise to lower the temperature; turn it counterclockwise to raise the temperature. Turn the screw just a little bit in the appropriate direction.

Adjust the temperature with the second type of knob by turning the dial on the back of the knob. (This dial is held in place with a screw or a clip that will need to be removed.) Raise the temperature setting by turning the dial counterclockwise; lower it by turning the dial clockwise. The notches are typically in 5 or 10-degree increments.
